Took a look at the more in-depth reviews from the contest, and here's an update based on that, which I hope fixes some problems.

Each team's middle building has been widened.

Dropdown has been opened up, lights are still there just in case.

The two barrels now have another on top of each other, not sure how exactly I should touch up on the drop to middle connector area, but I'll figure out someway to.

The bit of extension at middle was shortened

Now for something else:
Flank routes, I'm not entirely sure on how I should implement one. One idea is to modify this building:
What I think I could do is add a 2nd floor to it, and have a window that can overlook the control point, but that seems a bit extreme.

I think at the moment the issue is that the map is super narrow (like 2fort mid.) Adding flanks to that probably wont help: it'll be messy, and all you'll be able to do is attack from behind. In general the map needs to be a bit wider and more complicated - look at ravine or granary, say - very few discrete "flanks", but the combat arena is larger and more fun to fight in. As it is now, this map feels like world war 1 - just line up at opposite ends of the mid, and blast away until the others are dead. Making it wider would make that unviable.
